1. Field project construction. On the basis of the rice-fish breeding project, widen a section of ring-shaped ditch and dig it into a holding tank with a width of 8 to 10 meters and a depth of 1.5 meters or more. Shrimp farming and holding pools account for 15% to 20% of the total area of ​​rice fields. Inlet and outlet ports should be sealed with a tight mesh to prevent enemies from entering the water. 2. Shrimp stocking. Shrimp stocking is usually conducted from late June to early July. The size of the stocked shrimp requires 1.5 cm or more, and the stock of shrimp per mu is 1.5 to 20,000. .

Shrimp grows and provides rich natural food. In the feeding of artificial diets, 40% of animal diets may be used, ratio of botanical diets may be 60%, and feeds with more than 30% crude protein content may be fed. Feeding should be based on powder. . In July, August and September, some plant feeds can be fed. In October, more animal feeds should be fed. In particular, some crushing snails and animal organs can be fed. 4. Daily management.
